If this proves anything, it proves that the ancient way of building rigs will probably be brought back to the norm. This is speculation with regard to the floating and sinking rig problem.
Had this rig been of the rigid design with a foundation implanted in the sea bed, most likely the rig would not have sunk, and the pipe would not have failed at such a depth as it is now, and virtually impossible for man to withstand the water pressures of the location.
There still would be the geyser effect we're seeing now, but it would be a whole lot closer to depths that a man could survive in. IF it were under water at all.
Yes, I understand the leak is a mile or so below the surface, and yeah its a lot of steel/aluminum or whatever other material they could have chose to build the support structure from, but again, the cost of a mile of steel structure is a hell of a lot less than what its going to cost to clean up, as well as what its cost so far to have to repair this rupture.
Just my humble idle thought on this.
You may be right. But, I think they will most likely look at improving blowout preventors and the process of cementing and drilling so that it won't happen again.
The equivalent dilemma in aviation is do you make planes so that they can float in the event of a total engine faliure, and equip them with lifeboats; or do you make the engines so reliable that they never have to worry about a water landing. The industry has chose to go with more reliable engines, although the discussion about landing on water and the Hudson River incident shows that under ideal conditions, a water landing is still survivable, and every plane is equipped with life vests. You look at it the situation, and come with the most practical and cost-effective solution.
Ed and jmig have covered why we drill and what the consequences are well. Petroleum is not going away; the question is do we get it from hostile countries overseas, obtain it from far off the continental shelf, or closer to shore. It has been decided that the risk of incidents like this is too great for many locations closer to shore; so we have been banned from drilling there, and we are left with the first two choices.
Ask London of 1952 what life was like before natural gas and oil fired powerplants in more remote locations.

That wasn't that long ago; so reducing population is not the answer either.
However, as the oil sludge has made landfall in the Mississippi wetlands, part of the Florida Coast, and is heading North, along with the banning of fishing in over 40,000 square miles in the Gulf, the impact (even by Ken's 'Because the best policies are those that cause the least harm to society' standards) will be huge.
Aside from the loss of 35% of America's seafood fisheries, the knock on effect down the line from fishermen all the way to the consumer will be ugly.
Yes, it has made landfall, but in greatly diluted amounts, and much of it is non-toxic. I know, we are planning a trip to Galveston this weekend.
The effects are ugly, yes, but will probably be short lived. Watch and see. We can already say it is not the economic and environmental apocalypse that the early reporting said it would be.
And to all those that say humans dont effect the enviroment and that mother nature will "clean up" .. well thats utter bollacks and you need to get out away from the towns/citys etc and take a good look around you, now go back to town.
Sorry; it's a fact. Some tarballs washed up on the Florida Keys just in the past day or so, and guess what? An analysis of the oil determined that it is not from this oil spill. It either came from a ship -- or nature.
And I have spent the vast majority of my life in towns of 100,000 or less. Spindletop itself is on the edge of Beaumont, a town of about 100,000. The site of that original well is grass, trees, mosquitoes, birds, more mosquitoes, yet more mosquitoes, scattered pumpjacks, and even more mosquitoes; with US 287/69/96 passing by with the buinesses along it, and a railroad track; and not an environmental disaster area conveniently paved over with McDonalds and Wal-marts.
